S4 Pin Lockscreen - Can I change the style to S3?General

I recently got a Galaxy S4 after playing around with my Friends S3, but I have one complaint. I don't like the lockscreen layout/font..

On the S3, there are boxes around the digits, and they have better fonts. On my S4, I dislike all the fonts and there are no boxes around the digits - which this may be ok with a blank wallpaper - if the wallpaper is 'noisy' then it's hard to see the digits. See what I mean from the images below..

Is there any way I can change my s4 lockscreen to something similar to the S3.
